Her belly button is interesting. The depths of her belly button are confined to a vertical slit in the center. The way her belly button around that slit appears seems to vary. Many times it appears like an ovoid coin who's flat surface has been gently but firmly placed into the curving rounded form of her belly before having a keyhole sunk into its center. Other times rather than a "coin" there appears to be a more defined rim showing the border between belly and navel, after which the surface begins to dip inward toward the edge of he abyss. Still other times it appears as though aside from a "hood" at the top there is no outstanding marker of the boarder and the surface of her belly seems to proceed inward overlaying the territory of her navel before being swallowed up by depths at the center.
Thanks for posting this.
